INTRODUCTION 

The  observations  now  finally  published  in  this  volume  were  rqade  by  Professor  Peters,  during  the  decade 
beginning  in  1860,  with  the  i3-inch  Spencer  refractor  of  the  Litchfield  Observatory  of  Hamilton  College,  at  Clinton,1 
N.  Y.  They  were  prepared  in  tabular  form  by  their  author  for  publication,  and  his  412  pages  of  manuscript  tables, 
with  some  minor  omissions,  served  the  printer  as  copy.  It  is  supposed  that  Dr.  Peters  also  wrote  an  introduction 
describing  the  methods  of  observation  and  reduction,  but  unfortunately  this  seems  to  have  been  hopelessly  lost.  The 
fourteen  original  notebooks  entitled,  "  Observationes  astronomicae  originales  Maculae  Solis,"  are  preserved  in  good 
condition.  These  contain  for  each  date  a  pencil  sketch  of  the  appearance  of  the  spots  on  the  sun's  disk  (of  diam- 
eter about  ii  cm),  presumably  copied  from  the  larger  sketch  made  on  the  projection  screen.  They  also  record  the 
readings  from  the  chronograph  sheets  and  the  declination  scale,  together  with  the  clock  error. 

There  were  also  preserved  the  312  sheets  of  reductions,  representing  the  logarithmic  work  involved  in  deriving  the 
heliographic  latitude  and  longitude.  These  also  show  what  reduction  quantities,  calculated  from  the  adopted  ele- 
ments of  the  sun's  rotation,  were  used  each  day,  but  they  do  not  state  whence  the  elements  were  derived.  The  author 
doubtless  computed  tables  for  his  own  use  in  the  work,  but  they  have  not  been  found.  Investigation  has  shown  that 
he  employed  for  the  longitude  of  the  node  and  the  inclination  the  values  derived  by  Carrington  from  his  long  series 
of  observations,  and  recommended  by  him  for  future  adoption,  viz.,  N  =  73°4o'  for  1850,  I  =  7°  15'.  Dr.  Peters 
employed  a  different  period  and  a  different  epoch  from  those  of  Carrington,  and  reckoned  his  longitudes  in  the  oppo- 
site direction. 

In  order  to  give,  in  the  author's  own  words,  a  general  description  of  the  procedure  followed  in  the  observations, 
the  editor  has  translated  the  following  article  by  Dr.  Peters,  which  appeared  in  Band  64,  pp.  209-213  (1865),  of 
Astronomische  Nachrichten. 

"In  the  observations  which  have  been  made  here  since  May  1860  on  the  phenomena  of  the  solar  surface,  the 
principle  was  adopted  of  measuring  as  far  as  possible  everything  of  a  measurable  character  that  appeared  on  the  solar 
disk.  Therefore  in  the  first  instance  the  co-ordinates  were  determined  of  all  the  visible  spots  on  each  date,  and  these 
determinations  were  extended  to  all  the  isolated  dots  and  the  principal  members  of  groups;  also,  indeed,  to  many 
faculae  of  definite  form.  For  spots  of  considerable  extent  the  dimensions  of  the  umbra  and  penumbra  were  micro- 
metrically  determined,  generally  in  the  direction  of  declination  and  right  ascension.  An  accurate  sketch  was  always 
prepared  before  the  observations  and  was  a  necessary  auxiliary,  partly  for  convenience  as  a  reference  map  during  the 
observations  and  partly  for  the  comparative  study  both  of  the  changes  in  the  forms  of  the  spots  and  the  arrange- 
ments of  the  components  of  the  groups,  as  well  as  of  the  intensity  of  the  outbursts  and  their  relative  positions 
and  sequence.  In  the  winter  months  observations  were  made  on  every  favorable  day;  but  in  summer,  when  fair 
weather  can  be  more  safely  counted  on,  every  second  day  was  made  the  rule,  inasmuch  as  this  was  in  general  suffi- 
cient for  keeping  the  spots  under  watch  in  their  different  stages;  and,  moreover,  the  use  of  the  refractor  for  the  obser- 
vations at  night  always  required  a  somewhat  disturbing  exchange  of  the  attachments  at  the  eyepiece. 

"  For  the  observation  of  the  sun  the  image  was  projected  on  a  screen  which,  firmly  attached  to  the  refractor,  shared 
in  its  motions.  At  the  lower  end  of  the  large  tube  of  the  telescope  two  wooden  rings  were  put  on  at  some  distance 
apart;  each  having  four  corresponding  holes  through  which  wooden  rods,  only  slightly  elastic,  projected  about  one 
and  a  half  feet.  The  projection  board  was  fastened  in  notches  cut  in  these  rods  at  the  same  distance  from  the  eye- 
piece, and  was  held  in  place  by  the  springing  of  the  rods.  This  not  only  assured  the  perpendicularity  of  the  plane 
of  projection  with  respect  to  the  optical  axis  but  it  also  prescribed  that  the  distance  of  the  plane  of  projection  from 
the  eyepiece  was  always  the  same  when  the  latter  was  drawn  out  to  a  definite  mark  corresponding  to  the  sharpest 
image.  To  the  board  was  attached  a  rather  stiff  sheet  of  paper  on  which  had  been  drawn  two  systems  of  parallel 
lines  crossing  each  other  at  right  angles.  A  single  pin,  passing  through  the  center  of  these  lines,  attaches  the  paper 
at  the  point  where  the  center  of  the  image  of  the  field  of  the  telescope  falls.  By  turning  the  sheet  around  the  pin, 
the  lines  can  thus  be  made  parallel  to  the  directions  of  declination  and  hour  angle.  It  is  only  necessary  for  this  pur- 
pose to  let  the  sun's  limb,  or  any  distinct  spot,  run  across  parallel  to  one  of  the  system  of  lines,  preferably  along

the  central  line.  Since  the  angular  distances  from  the  center  are  projected  toward  the  tangent,  all  points  which  transit 
describe  hyperbolic  curves.  Thus  we  have  a  network  of  declination  and  time  threads.  For  measuring  differences 
of  declination  the  central  vertical  line  is  graduated  like  a  scale,  and  since  the  field  of  view  permits  the  whole  solar 
image  to  be  seen,  the  scale-reading  can  be  expressed  in  seconds  of  arc  with  the  aid  of  the  known  apparent  diameter 
of  the  sun.  As  one  division  has  a  linear  value  of  £  inch  (with  an  angular  value  of  about  23"),  the  tenths,  and  some- 
times the  twentieths,  can  readily  be  estimated.  The  differences  of  right  ascension  are  measured  by  the  diurnal  motion 
with  the  aid  of  a  chronograph.  In  order  to  avoid  a  correction  which  would  arise  from  the  projection  above  mentioned 
upon  the  plane,  the  transits  were  so  arranged  that  use  was  made  either  of  the  line  passing  through  the  center  of  the 
field  or  of  symmetrically  situated  pairs  of  lateral  threads. 

"  The  eyepiece  used  is  a  so-called  negative  one  of  the  Huyghens  form,  having  two  plano-convex  lenses  with  focal 
lengths  of  3.90  and  1.75  inches.  The  magnification  is  approximately  75,  and  the  field  of  view  is  38',  so  that  it 
embraces  on  each  side  3'  more  than  the  whole  solar  disk.  The  eyepiece  is  drawn  out  i  .  45  inches  in  order  to  make 
the  image  distinctly  visible  at  the  distance  of  the  projection  board  from  the  eye  lens  —  15.43  inches.  The  actual  mag- 
nification of  the  image  is  here  about  140  times,  or  the  number  which  we  obtain  if  the  magnification  given  above  is 
multiplied  by  the  quotient  of  the  distance  of  the  table  divided  by  the  distance  of  distinct  vision  (7  to  8  inches). 

"  Further  explanation  is  required  of  the  conversion  of  the  scale-distance  into  arc  whereby  the  distance  in  declina- 
tion of  a  spot  from  the  sun's  center  is  measured.  On  account  of  the  size  of  the  angles  under  which  the  rays  fall  upon 
the  paper,  the  tangents  can  no  longer  be  held  to  be  proportional  to  the  arc,  and  the  value  of  a  scale-division  decreases 
from  the  center  of  the  field  toward  the  edge.  These  angles  have  their  vertex  at  the  position  for  the  eye  ;  or  rather,  in 
this  case,  where  the  eyepiece  is  drawn  out,  in  more  general  terms  in  the  point  through  which  all  rays  pass  after 
emergence  from  the  eyepiece,  and  therefore  the  distance  of  this  point  from  the  board  is  concerned.  Instead  of  com- 
puting this  from  the  dimensions  of  the  system  of-  lenses,  we  in  practice  get  a  knowledge  of  this  most  simply  by 
pointing  the  telescope  toward  the  brightly  illuminated  sky  and  rendering  the  emergent  pencil  visible  (as  by  blowing 
smoke  upon  it).  Let  us  denote  this  distance,  expressed  in  scale-divisions,  by  D,  the  angle  of  the  cone  of  the  sun's  disk 
formed  at  the  intersection  by  G;  g  is  similarly  the  angle  at  the  same  point  between  the  spot  and  the  sun's  center,  p  is 
the  apparent  radius  of  the  sun,  S  its  magnitude  read  off  from  the  table,  5  the  distance  of  the  spot  from  the  sun's 
center.  Then  we  have

But  the  last  is  the  difference  in  declination  of  the  spot  and  the  sun;   therefore

A  small  table  of  double  entry,  with  the  arguments  $  and  p,  gives  AS  directly.     For  the  apparatus  here  D  =  i  igPo,  and 
on  the  average  G  =  19°  30'.    The  diameter  of  the  solar  image  measures  somewhat  over  ten  inches  on  the  paper. 

"  The  transits  for  right  ascension  are  as  a  rule  taken  four  times,  twice  before  and  twice  after  reading  off  the  declina- 
tions, each  time  over  one  thread.  When  the  number  of  spots  is  large,  as  has  often  been  the  case  in  recent  years  ;  and 
several  groups  fall  at  the  same  hour-angle,  each  section  has  to  be  determined  for  itself.  The  usefulness  of  the 
chronograph  should  be  particularly  recognized  in  such  cases  as  this  where  the  objects  follow  each  other  in  rapid 
succession  —  often  separated  by  only  a  fraction  of  a  second.  The  clock  is  regulated  to  mean  time  so  that  the 
differences  of  right  ascension  are  obtained  without  further  reduction,  since  the  departure  of  the  rate  from  apparent 
solar  time  does  not  come  into  consideration,  never  exceeding  ^ViP  The  accuracy  obtained,  as  well  as  the  sim- 
plicity of  the  reduction  and  the  whole  procedure  will  be  the  more  readily  perceived  from  the  following  example. 
The  separate  groups  of  each  day  are  distinguished  in  order  of  right  ascension  by  the  capital  letters,  the  separate 
spots  of  the  groups  in  the  same  order  by  the  small  letters  with  the  attached  exponents;  but  the  most  conspicu- 
ous spot  of  each  group  is  assigned  the  letter  without  an  exponent;  different  nuclei  in  the  same  penumbra  receive 
subscripts.  This  mode  of  designation  is  preferable  to  that  of  current  numbers.

"The  mean  of  the  times  is  oh  46™  7?2,  and  the  correction  of  the  clock  +8*5,  so  that  the  observations  as  taken 
are  valid  for  oh  46™  15*7  mean  time. 

"The  probable  error  of  an  observation  was  deduced  to  be  ±o!n  from  a  number  of  determinations  of  the  time 
of  transit  of  the  sun's  radius,  by  means  of  the  deviations  from  the  average  of  each  day.  For  a  spot  the  error  in 
general  will  be  somewhat  greater;  and  since  on  the  one  hand  this  has  to  be  multiplied  by  a  number  larger  than 
V  2,  while  on  account  of  being  the  average  of  four  determinations,  it  must  on  the  other  hand  be  divided  by  2, 
we  may  estimate  the  accuracy  of  the  determination  as  i  f 5.  The  probable  error  in  declination  will  be  about  the 
same,  since  here  the  limit  of  reading  is  from  ^  to  -^  of  a  scale-division." 

The  formulae  now  involved  are  simply  derived  by  applying  the  three  fundamental  formulae  of  spherical  trigo- 
nometry to  the  triangle  having  as  its  vertices  the  spot,  the  sun's  pole  and  the  center  of  the  disk. 

Let  Aa  and  AS  represent  the  differences  in  right  ascension  and  declination  of  the  spot  and  the  center  of  the  disk. 
Let  p  be  the  "zenith  distance  of  the  earth  as  seen  from  the  spot,"  and  n  be  the  geocentric  distance  of  the  spot  from 
the  center  of  the  disk.  Then  n=p  sin  p,  where  p  is  the  sun's  radius.  P  is  the  symbol  for  the  position  angle  of  the 
spot,  reckoned  from  the  east  through  the  north,  and  N  is  the  position  angle  of  the  sun's  pole.  B  is  the  heliographic 
latitude  of  the  spot,  B0  that  of  the  center  of  the  disk;  L  and  L0  are  the  heliographic  longitudes  of  the  spot  and  of  the 
center  of  the  disk  from  the  node. 

Then  we  have  .  „

cosBsm(L—L0)=sin(p—n)cos(P—N)  . 
For  adaptation  to  logarithmic  computation,  let 

g  sin  £=sin  (p—n)  sin  (P—N) ,

Then  we  get  sin  B = g  sin  (B0 + £) ; 

cos  (L — L0)  cos  .B = £  cos  (B0 + £) ; 
sin  (L-L0)  cos  B= sin  (p- n)  cos  (P-N) .' 

1  It  seems  that  it  would  have  been  more  expeditious  to  use  addition  and  subtraction  logarithms  and  employ  the  first  and  third  of  the  funda- 
mental formulae,  solving  (L—L0)  by  the  tangent  only  when  necessary.

The  scheme  of  computation  explains  itself.    In  the  ninth  column  the  author  sometimes  gives  «  and  sometimes 

.  — - ,  for  either  of  which  a  table  with  argument  sin  p  could  easily  have  been  constructed.    The  elements  of  the 
sinp 

sun's  rotation,  as  employed  by  the  author,  are: 


Intro&uciion 


Vll 


Longitude  of  the  ascending  node  of  sun's  equator  =  73°  40'  for  1850. 
Inclination  of  axis  to  axis  of  ecliptic  =  7°  15'. 

(These  were  the  values  recommended  by  Carrington.) 
Mean  daily  rotation  angle       =842.'o4  =  i4?o34, 
or  Mean  sidereal  rotation  period  =25.652  days. 

This  value  was  derived  by  Dr.  Peters  from  his  observations  of  803  positions  of  286  spots  made  at  Naples  in  the 
thirteen  months  from  September  1845  to  October  1846,  as  stated  in  his  paper  read  at  the  Providence  meeting  of  the 
American  Association,  1855. 

"First  solar  meridian  that  in  which  the  earth  was  at  Greenwich  mean  noon  1860  January  o." 

"  I  reckon  the  longitudes  in  the  sense  that  any  point  of  the  heavens  would,  as  a  result  of  the  sun's  rotation,  suc- 
cessively pass  increasing  meridians.  This  would  correspond  on  the  earth  to  counting  longitudes  westward  as  posi- 
tive" (A.  N.,  71,  241,  1868). 

"To  avoid  ambiguity,  it  may  be  prefaced  that  the  heliographical  longitudes  are  counted  in  the  direction  opposite 
to  that  of  the  rotation  of  the  sun  (or  what  corresponds  upon  the  earth  from  the  east  toward  the  west),  and  a  spot  is 
said  to  be  following  another  neighboring  one,  when  the  former  has  greater  heliographical  longitude, — when  by  the  rota- 
tion of  the  sun,  it  will  come  later  into  the  same  heliocentric  position  in  regard  to  the  fixed  stars  than  the  preceding 
spot."  (Astronomical  Notices,  No.  29,  March  18,  1862.) 

In  order  to  facilitate  the  comparison  of  longitudes  given  by  Peters  with  those  of  Carrington  and  those  at  Kew 
and  at  Greenwich,  a  conversion-table  is  given  for  each  date  of  observation  by  Peters.  A  rigorous  comparison  can- 
not be  made  with  Carrington's  positions,  as  the  latter  were  derived  from  assumed  values  of  the  longitude  of  the  node 
and  inclination,  to  which  small  corrections  were  obtained  by  Carrington  from  his  whole  series  of  observations.  The 
difference  is  not,  however,  of  any  consequence  in  the  identification  of  spots. 

The  following  table,  which  has  been  calculated  by  Mr.  Philip  Fox,  gives  the  angular  distances  between  the 
prime  meridians  of  the  systems  of  Carrington  and  Peters  for  Clinton  noon  of  each  day  when  Peters  observed.  The 
conversion  is  effected  by  merely  subtracting  Peters'  L'  from  the  tabular  value  for  the  date  (increased  by  360°  where 
necessary),  after  due  allowance  has  been  made  for  the  difference  in  time  of  observation  and  in  longitude  of  the  place 
of  observation. 

TABLE  OF  ANGULAR  DISTANCES  BETWEEN  THE  PRIME  MERIDIANS  OF  PETERS  AND  CARRINGTON 
For  Clinton  noon  of  each  day  on  which  Peters  observed.

COMPARISON  OF   POSITIONS  OF  SPOTS  OBSERVED   BY  PETERS  WITH  THOSE  OBTAINED  BY 

CARRINGTON  AND  AT  KEW 

Carrington's  classic  series  of  observations,  entitled  "Observations  of  the  Spots  on  the  Sun  from  November  9, 
1853,  to  March  24,  1861,  Made  at  Redhill"  (published  in  1863),  overlaps  that  of  Dr.  Peters  during  the  period  from 
May  23,  1860,  to  March  24,  1861,  in  which  interval  observations  were  made  by  the  two  observers  on  the  same  day 
in  fifty-two  instances.  Carrington's  telescope  had  an  aperture  of  4.5  inches  and  a  focal  length  of  52  inches.  He 
observed  transits  of  the  projected  image  across  bars  in  the  focal  plane  inclined  45°  to  the  direction  of  the  diurnal 
motion. 

The  Observations  made  at  Kew1  with  the  photoheliograph,  which  in  effect  form  a  continuation  of  the  Redhill 
series,  were  begun  on  February  7,  1862,  and  were  continued  for  ten  years.  They  accordingly  cover  the  last  eight 
years  of  Dr.  Peters'  work.  The  interval  not  included  by  the  English  observations  was  from  March  25,  1861,  to 
February  6,  1862,  although  the  Kew  instrument  was  being  employed  in  a  preliminary  way  during  this  time,  so  that 
the  gap  might  perhaps  be  fairly  bridged  without  the  records  of  Dr.  Peters.  The  Kew  photoheliograph  had  an  aper- 
ture of  3 . 5  inches  and  a  focal  length  of  50  inches.

Observed  with  the  Kew  Photoheliograph  During  the  Years  1862  and  1863.  Philosophical  Transactions,  159,  i-no,  1868. 


xii  Introduction 

Spoerer's  observations,  as  published  (1874)  in  his  first  extensive  memoir,  "  Beobachtungen  der  Sonnenflecken 
zu  Anclam,"  cover  the  period  from  January  i,  1861,  to  September  7,  1867.  He  first  used  a  "3^-foot"  telescope 
and  ring  micrometer;  later  he  employed  a  "seven-foot"  telescope,  with  a  network  of  ruled  lines  in  the  focal  plane. 

It  is  thus  evident  that  the  instrument  employed  by  Peters  was  superior  to  those  of  his  contemporaries,  and  his 
method  of  reduction  was  not  less  rigorous.  A  comparison  of  his  positions  of  spots  with  those  obtained  elsewhere 
on  the  same  dates  is  therefore  of  interest.  Inasmuch  as  Spoerer  used  quite  different  elements  of  the  sun's  axis, 
and  a  different  period  of  rotation  from  those  employed  by  the  other  observers  here  involved,  a  new  reduction  of  his 
positions  would  be  necessary  before  any  comparison  could  be  made.  This  comparison  is  therefore  not  feasible  here. 

In  the  case  of  Carrington's  measures  the  conversion  table  given  above  serves  to  make  the  positions  of 
Peters  conform  in  longitude  with  those  of  Carrington,  except  for  the  difference  in  the  value  of  the  longitude  of 
the  node.  For  the  purpose  of  comparison,  108  spots  observed  on  fourteen  days  in  1860  by  both  Carrington  and 
Peters  were  collected,  only  such  spots  being  employed  as  could  be  regarded  as  certainly  identified.  The  results 
are  as  follows: 

MEAN   OF  DIFFERENCES,   PETERS-CARRINGTON 

In  longitude,  with  respect  to  sign +39-'2 

In  longitude,  without  respect  to  sign 45 . 2 

In  latitude,  with  respect  to  sign +13.4 

In  latitude,  without  respect  to  sign 28.8 

Inasmuch  as  Carrington  actually  used  a  value  for  N  smaller  by  47'  than  he  subsequently  derived  from  his  whole 
series  of  observations,  his  values  in  longitude  should  be  increased  by  that  amount.  Hence  the  outstanding  mean 
difference  in  longitude,  P.-C.,  reduced  to  the  same  longitude  of  node,  becomes  —8'.  Carrington's  use  of  1  =  7°  10' 
instead  of  1  =  7°  15'  introduces  a  slight  difference  in  the  individual  latitudes,  but  this  is  practically  balanced  in  the 
series  of  observations  compared. 

We  therefore  conclude  that  there  is  no  systematic  difference  between  the  positions  of  Carrington  and  Peters 
amounting  to  more  than  o?2 — a  satisfactory  agreement.  Accidental  differences  averaging  from  o?5  to  o?75  occur, 
however.  These  differences  are  doubtless  due,  in  large  measure,  to  the  fact  that  two  observers  can  hardly  agree 
in  setting  upon  the  nucleus  of  so  indefinite  an  object  as  a  sun-spot.  The  actual  changes  in  the  spots  between  the 
time  of  their  observation  in  England  and  in  America  are  also  involved. 

The  observations  at  Kew  and  Clinton  are  strictly  comparable,  after  the  latter  are  corrected  in  longitude  for 
direction  and  rotation-period  by  our  conversion  table.  For  the  purpose,  114  spots  measured  at  both  stations  on 
21  days  between  February  7,  1862,  and  July  2,  1863,  were  used,  with  these  results: 

MEAN   OF   DIFFERENCES,    PETERS-KEW 

In  longitude,  with  respect  to  sign +  7  .'6 

In  longitude,  without  respect  to  sign 19.0 

In  latitude,  with  respect  to  sign —  7.0 

In  latitude,  without  respect  to  sign 17.4 

We  may  thus  infer  that  differences  of  a  systematic  nature  amount  to  scarcely  more  that  o?  i  in  either  co-ordinate, 
while  the  accidental  differences  average  o?3.  The  better  accordance  than  that  in  case  of  Carrington  is  presumably 
due  to  the  superiority  of  the  Kew  positions.  Very  considerable  differences,  however,  are  seen  in  the  Kew  measure- 
ments of  the  same  spot  when  two  photographs  were  made  on  the  same  day.  We  find  that  on  ten  of  the  twenty- 
one  days  used  in  the  comparison  of  Peters  and  Kew  such  duplicate  observations  were  made  at  Kew,  the  average 
interval  between  the  two  plates  being  0^064.  A  comparison  for  61  spots  gave  the  following  results,  expressed  in 
the  sense  first  measure  minus  second  measure : 

In  longitude,  with  respect  to  sign —  11.3 

In  longitude,  without  respect  to  sign 17 -2 

In  latitude,  with  respect  to  sign —  0.3 

In  latitude,  without  respect  to  sign 9.2 

The  accidental  differences  in  the  longitudes  of  the  two  Kew  plates  are  therefore  practically  of  the  same  magnitude 
as  those  of  Peters-Kew;  while  those  in  latitude  are  only  one-half  smaller.  This  clearly  tends  to  confirm  the  high 
opinion  as  to  the  accuracy  of  the  positions  of  Dr.  Peters  which  a  careful  examination  is  certain  to  give  to  anyone. 


Introduction  xiii 

The  regret  is  increased  that  his  observations  could  not  have  been  published  shortly  after  they  were  concluded  and 
during  his  lifetime.  It  is  evident  that  they  are  of  such  a  degree  of  accuracy  that  they  might  safely  be  made  the  basis 
of  investigations  of  various  problems  of  the  sun's  rotation,  aside  from  their  value  as  records  of  the  solar  activity. 
The  editor  acknowledges  his  indebtedness  to  his  wife  for  assistance  in  reading  the  proofs,  and  to  Mr.  Philip 
Fox  for  aid  in  various  ways;  also  to  Professor  Samuel  J.  Saunders,  of  Hamilton  College,  for  his  thorough  but 
unavailing  searches  for  the  missing  papers  of  Dr.  Peters. 

YERKES  OBSERVATORY 

THE  UNIVERSITY  OF  CHICAGO 

September,  1907 


HELIOGRAPHIC   POSITIONS  OF   SUN-SPOTS 


In  the  following  table  of  observed  positions  of  sun-spots,  the  time  given  is  Clinton  mean  time  (astronomical)  for 
the  civil  date.  The  first  column  gives  the  current  designation  of  the  spot  by  a  letter,  as  used  on  the  author's  draw- 
ings and  chronograph  records.  Capital  letters  are  used  for  groups,  small  letters  for  spots,  letters  with  subscripts  for 
different  nuclei  within  the  same  penumbra,  letters  with  exponents  for  different  spots  in  the  same  group;  a  letter  with- 
out exponent  or  subscript  is  assigned  to  the  most  conspicuous  spot  of  the  group.  Aa  is  the  observed  difference  in  time 
between  the  transit  of  the  spot  and  the  mean  of  the  transits  of  the  limbs,  or  is  the  difference  of  right  ascension  of  spot 
and  center  of  disk.  AS  is  the  corresponding  difference  in  declination.  In  cases  of  large  nuclei,  the  edges  were  often 
observed,  designated  by  «  and  5  for  declination;  the  means  of  the  Aa  and  AS  were  then  used  in  the  computations. 
The  size  of  the  nuclei  may  be  derived  from  these  data.  Measures  were  also  frequently  made  on  the  margins  of  the 
penumbrae,  but  heliographic  positions  were  not  computed,  and  those  measures,  as  well  as  the  very  infrequent  meas- 
ures of  faculae,  have  been  here  omitted.  The  heliographic  latitude  is  given  in  the  next  column  under  the  heading  b. 
In  the  column  headed  L  is  found  the  longitude  from  the  node;  under  L',  the  heliographic  longitude.  The  letter  in 
the  last  column  serves  to  identify  the  spot  on  the  next  following  date.  In  cases  where  the  identification  was  regarded 
as  doubtful  by  author  or  editor,  the  letter  has  been  omitted. 

The  gap  in  the  observations  from  August  17,  1863,  to  November  2,  1864,  is  not  due  to  a  deficiency  in  the  records, 
but  to  a  prolonged  absence  of  Dr.  Peters  in  Europe.

SUMMARY   BY   DATES   OF  NUMBER  OF  SPOTS  OBSERVED 


This  summary  was  extracted  from  the  fourteen  observ- 
ing books  of  Dr.  Peters,  each  of  which  contained  such  a 
list  of  the  numbers  of  spots  observed.  A  resume"  up  to 
August  17,  1863,  was  published  in  his  article  in  Astro- 
nomische  Nachrichten,  64,  213-218,  1865,  with  the  fol- 
lowing words  of  description  (translated): 

"The  following  table  contains  for  each  observing  day 
the  number  of  spots  of  which  the  co-ordinates  were  deter- 
mined as  stated.  To  these  are  also  added  the  days  on 
which  variable  weather  permitted  the  spots  to  be  sketched 


only  and  not  to  be  measured.  For  these,  the  numbers 
signify  merely  countings  from  the  sketches,  and  they  are 
therefore  enclosed  in  parentheses.  The  observations  were 
interrupted  in  August,  1863,  by  a  long  trip  to  Europe, 
and  were  not  begun  again  until  the  beginning  of  Novem- 
ber of  last  year.  The  re'sume'  may,  therefore,  embrace 
for  now  only  the  first  series.  Inasmuch  as  some  time  will 
be  required  for  the  complete  publication  I  shall  be  ready, 
upon  request,  to  communicate  the  details  for  separate 
days  by  letter."

C.  H.  F.  Peters 


Dr.  Peters'  notes  include,  beside  the  statement  of  the  weather  conditions,  references  to  Wilson's  theory  of  the 
depression  of  sun-spots.  A  total  of  172  spots  are  mentioned  in  this  connection,  of  which  141  favor  Wilson's  theory, 
and  31  are  opposed  to  it.  To  make  these  observations  available  for  any  possible  discussion  on  this  point,  the  dates 
are  here  given,  with  the  letter  identifying  the  spot.

Aside  from  the  references  to  Wilson's  theory,  the  notes  contain  one  other  item  which  perhaps  ought  to  be  recorded, 
viz.,  July  s,  1868:  Spot  a.  "A  notch  on  the  sun's  limb  formed  by  the  elevation  of  photospheric  matter.  The  sun's 
limb  very  sharply  defined."
